Midterm 1, 5 problems, 15 points each.
1. Solve for x
a(a-1)x = a2
where a is a given number.
2. xy -> max, |x-1| + |y-2| <=
5.
3. Write LP in standard and canonical forms:
f= x+ y -> max, 0 <= x <=
9, y <= 0.
4. Solve for x,y:
3 | x | 2 | y | |
x | -1 | y | -2 | = x |
0 | 3 | x | 4 | = -3 |
5. Pivot:
x | y | 4 | 3 | |
4 | 5 | 2 | x | = y |
-1 | 2* | 0 | 0 | = 2 |
